The use of molecular biology and genomics tools in plant biology research has greatly expanded our understandingof the molecular mechanisms that underlie plant development and physiology.The successful establishment of researchresources such as mutant populations has led to progress in a variety of fields,including plant reproductive develop-ment,signal transduction,hormone functions,defense responses and epigenetic control.In the future these advanceswill potentially facilitate crop improvement through molecular breeding.  相似文献

This review focuses on the contribution of electron tomography-based techniques to our understanding of cellular processes in plant cells. Electron microscopy techniques have evolved to provide better three-dimensional resolution and improved preservation of the subcellular components. In particular, the combination of cryofixation/freeze substitution and electron tomography have allowed plant cell biologists to image organelles and macromolecular complexes in their native cellular context with unprecedented three-dimensional resolution (4-7 nm). Until now, electron tomography has been applied in plant cell biology for the study of cytokinesis, Golgi structure and trafficking, formation of plant endosome/prevacuolar compartments, and organization of photosynthetic membranes. We discuss in this review the new insights that these tomographic studies have brought to the plant biology field.  相似文献

Journal of Systematics and Evolution (JSE) has just debuted with its first issue. While it continues the tradition of its predecessor, Acta Phytotaxonomica Sinica (APS), in publishing papers in taxonomy and systematics, it is also embracing new trends in evolutionary biology to include papers in molecular evolution, evolutionary genomics, evolutionary developmental biology, evolutionary ecology, biogeography, and other related fields. We sincerely hope that this expanded journal scope will serve our science and community better. This journal has a long and rich history, It was established in 1951 by consolidating four journals that were founded by early Chinese botanists and published intermittently from the 1920's until the late 1940's: Bulletin of the Fan Memorial Institute of Biology, Botanical Series; Contributions from the Institute of Botany, National Academy of Peiping; Botanical Bulletin of Academia Sinica; and Contributions from the Biological Laboratory of the Science Society of China, Botanical Series. The journal has witnessed the founding and development of modem botany, plant taxonomy, and plant evolutionary biology in China over the last century.  相似文献

Plants--of the botanical kind--are not often mentioned in 'The State of the Union' addresses by US Presidents, but when they are, it can have global impacts on plant biology research. In the 1990s, President Clinton ridiculed government support of research on 'plant stress' in one of his addresses, confusing psychological stress with the devastating effects of drought, salinity, and other environmental stresses on agricultural productivity. A decade later, President Bush mentioned the S word (switchgrass) in connection with alternatives to petroleum, thereby encouraging the US Department of Energy to invest heavily in research to understand plant cell walls and to develop efficient processes to harness the sun's energy, which is stored on a massive scale in plant cell walls.  相似文献

A workshop on "Chips, Computers and Crops" was held in Hangzhou, China during September 26-27, 2008. The main objective of the workshop was to bring together China and UK scientists from mathematics, bioinformatics and plant molecular biology communities to exchange ideas, enhance awareness of each others' fields, explore synergisms and make recommendations on fruitful future directions in crop science. Here we describe the contributions to the workshop, and examine some conceptual issues that lie at the foundations and future of crop systems biology.  相似文献

Actin cytoskeleton undergoes rapid reorganization in response to internal and external cues. How the dynamics of actin cytoskeleton are regulated, and how its dynamics relate to its function are fundamental questions in plant cell biology. The pollen tube is a well characterized actin-based cell morphogenesis in plants. One of the striking features of actin cytoskeleton characterized in the pollen tube is its surprisingly low level of actin polymer. This special phenomenon might relate to the function of actin cytoskeleton in pollen tubes. Understanding the molecular mechanism underlying this special phenomenon requires careful analysis of actin-binding proteins that modulate actin dynamics directly. Recent biochemical and biophysical analyses of several highly conserved plant actin-binding proteins reveal unusual and unexpected properties, which emphasizes the importance of carefully analyzing their action mechanism and cellular activity. In this review, we highlight an actin monomer sequestering protein, a barbed end capping protein and an F-actin severing and dynamizing protein in plant. We propose that these proteins function in harmony to regulate actin dynamics and maintain the low level of actin polymer in pollen tubes.  相似文献

Human disturbance and climate change have increased the risk of extinction for rare and endangered wild plant species.One effective way to conserve these rare and endangered species is through reintroduction.In this review,we summarize the advances in wild plant reintroduction from five perspectives:the establishment of reintroduction biology as an important tool for biodiversity conservation;the importance of genetic diversity in reintroduction;reintroduction under global climate change;recruitment limitation in reintroduction;and reintroduction and ecological restoration.In addition,we consider the future of plant reintroduction strategies.  相似文献

Systematics and evolution are the most comprehensive fields in biological sciences,and unify all areas of biology by providing a conceptual framework for interpreting biological diversity.Journal of Systematics and Evolution (JSE),established in 1951 as Acta Phytotaxonomica,has a long history of publishing papers on plant taxonomy.In 1954 (Vol.3),the journal name was changed to Acta Phytotaxonomica Sinica.Half a century later,in 2008,the current name was approved and used and the journal became all-English in 2009,with the expanded scope to include molecular evolution,evolutionary genomics,evolutionary developmental biology,evolutionary ecology,biogeography,and other related fields,beyond the core area of plant taxonomy.  相似文献
